What is the different about the two kinds of metal on the bimetallic strip of a thermostat coil?
When the two metals are heated or cooled through the same change in temperature,
one of them expands or contracts more than the other one does. That's why, when
they're glued back-to-back, the combined strip develops a curve in it when it's heated.
It curves away from the one that expands more, and toward the one that expands less.

What is the two metal pieces in a thermostat?
The two metal pieces in a thermostat are typically made of bimetallic strips. These strips have different coefficients of thermal expansion, causing them to bend in response to temperature changes. When the temperature reaches a certain point, the bimetallic strips cause the thermostat to switch on or off.
Does specific heat capacities have anything to do with different metals in a bimetallic strip used in a thermostat?
The principal thing is linear expansion rates as temperatures rise, different metals have different rates of expansion. In a bimetallic strip, one layer of one metal is fused onto one layer of another metal with a different linear expansion rate, when heated the strip will curve along its length due to the different expansion rates, the greater the temperature rise, the more the curvature, this movement is used to trip a switch.
Why are bimetallic strips useful in thermostas?
Bimetallic strips are useful in thermostats because they bend when heated, allowing them to trigger switches or valves to control temperature. The differential thermal expansion of the two metals in the strip enables precise temperature sensing and regulation within a thermostat.
What contains a small piece of metal that bends when it gets hot?
A thermostat contains a small piece of metal called a bimetallic strip that bends when it gets hot, allowing it to regulate temperature by opening or closing a circuit.
What is a bimetallic thermometer?
A bimetallic thermometer uses a bimetallic strip wrapped into a coil. This strip usually consists of either steel and copper or steel and brass. A bimetallic thermometer is a type of thermometer made with a couple metal strips. They have differing thermal expansions that are brazen together. Any distortion in this apparatus caused by variations in the temperature is used to measure the temperature.

What is helical bimetallic strip?
A helical bimetallic strip is two strips of metal with differing boiling points that have been fused together, spiraling upwards around a central object. When heat is applied to the bimetallic strip, the different chemical properties in each metal strip will cause them to expand, forcing the helical strip to expand upwards.

How is a bimetallic strip used in a thermostat?
A bimetallic strip is used in a thermostat, by concealing it inside. When the temperature goes up, the bimetallic strip expands, and turns on the circuit for the AC/compressor ,to make the temperature cooler inside wherever the thermostat is.Two metal strips of differing thermal expansion are bonded together. Because the expansion is different the metals expand by different amounts. When heated the strip therefore has to bend, the one with the greater expansion on the outside of the curvature. As the strip bends it can either make or break a circuit contact depending on the configuration of the circuit, switching on of off the current. The reverse is true when the strip cools again.
When a bimetallic strip is heated it bends toward the metal with the thermal expansion?
When a bimetallic strip is heated, the metal with the higher coefficient of thermal expansion expands more than the other metal, causing the strip to bend towards that metal. This bending is due to the unequal expansion and contraction of the two metals when exposed to different temperatures.
How does bimetallic work in an electric iron?
A bimetallic strip is a strip made from 2 different metals. It is designed to bend one way if it is warm and the other way if it is cold. The hotter it gets, the more it bends. In any thermostat, the electrical contacts bend apart as the target temperature is reached. The only difference between a heating thermostat and a cooling thermostat is which side of the bimetallic strip faces the other contact. In a heating appliance, the thermostat knob turns a screw to add resistance to the motion of the contacts so they must get hotter to separate as the screw is tightened. So the tighter the screw is turned, the hotter the appliance is allowed to get before the contacts separate.
What are the function of Bimetallic thermometer?
A bimetallic thermometer has a coil of metal strips in it. The metal strips are made of two different materials that expand/contract at different rates. Because they're connected together at one end, when the metals warm up or cool down, the coil changes shape. You use a bimetallic thermometer when you want an electrical circuit to close due to a change of temperature.
What are the 2 metal strips in a battery called?
